Product Overview
ST25R3917-AQWT is a high performance NFC forum reader. This NFC IC is optimized for POS terminal applications. It enables the fastest EMVCo 3.0 certification cycles possible, even under harsh conditions, with antenna around noisy LCD display. It contains a low power capacitive sensor to detect the presence of a card without switching on the reader field. It also contain a low power RC oscillator and wake-up timer to automatically wake-up the reader after a selected time period and check for a presence using one or more low power detection of card (capacitive, phase or amplitude). This EMVCo reader is widely used in applications like NFC forum compliant NFC universal device, EMVCo 3.0 compliant contactless payment terminal, ISO14443 and ISO15693 compliant general purpose NFC device, FeliCa™ reader/writer, support of all five NFC forum tag types in reader mode, support all common proprietary protocols, such as Kovio, CTS, B’.
